The bureau has invited interested parties to submit tender documents for the deployment of underground cables. The locations include areas such as Ratnapark, Maitighar, Thapathali, Chabahil and Thamel.

"Deploying underground cables is a costly thing, so we will only deploy on the city's main road," said Manoj Silwal, director of the project office of the Nepal Electricity Authority.

The power bureau decided to deploy underground cables to remove overhead lines in order to improve the distribution system. This is part of the $ 180 million power transmission and distribution project funded by the Government of Nepal and the Asian Development Bank.

Transmission and distribution projects aim to meet the growing energy needs of Kathmandu and increase the capacity and reliability of distribution networks through automated networks, laying underground cables, erecting overhead lines with insulated cables and installing smart meters. 180 million US dollars financing, the Asian Development Bank will provide 150 million US dollars of soft loans, the Nepal government will provide the remaining funds.

According to the announcement issued by the Nepal Electricity Authority, the project will be open tender to select the contractor laying underground cable. The tender will be conducted in accordance with the Asian Development Bank's "single-stage dual-envelope bidding process", which must be submitted in both envelopes for technical and financial quotations.

The tender will be open on October 6 at the time of the bidder's presence, and the financial tender will remain closed and remain in the locked box.

The bureau will only make financial tender for bidders with technical qualifications. After the contract is awarded to the lowest bidder qualified for technical qualification, the financial tender documents of the technically unqualified bidders will be returned in unopened state.

The electricity bureau will use a horizontal installation grid system to lay the underground cable, as this will cause less damage to the road. The system is designed to drill a pit in one place, allowing the cable to lay a distance of 100 meters.

"We are also aware that road traffic should not be affected by construction, so we will be asphalt as soon as the cable is laid," Silwal added.

According to the Bureau of Electricity, the main reason behind the removal of existing overhead lines and the installation of underground cables is to improve the reliability of the distribution system. The power distribution system of the electricity bureau is very fragile, leading to a sudden power failure even in the case of adequate power supply.

The existing distribution network in the Kathmandu Valley can not support loads of more than 400 megawatts. The electricity bureau plans to upgrade the system to support up to 2000 megawatts of electricity load.
